Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on the model and manufacturer the process could be as simple as using an additional key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian car manufacturers have programming protocols that they share with auto tool makers to allow them to develop hardware and software for locksmiths in the automotive industry to use.
